Lette/rs Patent No. 93,012, dated July 27, 1869; antedated 4.Tally 16, 1869.

IMPROVE!) METHOD OF lli/IAN'UFACTURING vINEG-AR.

The Schedule ,referred to in these Letters Patent and making pax-tro! the same.

To all whom it may concern:

Be it known that .I, FRANCIS SCHLEFER, of the city andcounty of San Francisco, State of California, have invented an Improved Method `of Manufacturing Vinegars; and I do hereby declare the fol-A lowingdescription and accompanying' drawings lare sufcient to enable any person skilled in the art or science to which it most nearly appertains, to make and use my said invention or improvements without further invention or experiment..

My invention consists in mingling, with alcoholic and vinegar-vapors, oxygen in sucient quantities to produce acetication rapidly, whereby the conditionsvunder which vinegar is obtained are more profitable than by the common method or process.

In order to more fully illustrate and describe my method of manufacturing vinegar, reference is had to the accompanving drawing and letters marked thereon, forming a part of this specification, of 'whrcn- Figure 1 is a sectional elevation of fig. 2, cu't lougitudinally.

Figure 2 is a plan or top View.

A represents a compartment for the diluted alcohol or fermented liquor.

Another com partment, B, in which vinegar is placed, is situated above the first, A, the two being separated by a diaphragm, C, through which a pipe, D, passes.

A cap, E, larger than the pipe, D, is placed over it, and is attached to the diaphragm, leaving notched openings around its base.

The vinegar compartmentis divided by a perforated bottom, F, making a third compartment, in which is placed a quantity oi' shavings, which are saturated with vinegar, say, from thirty (30) to forty (40) gallons, or with a suiiicient quantity for the capacity of the -gcnerator F.

The generator isprovided with suitable openings a a a and b b b, through which to introduce 'and draw I ot the liquid, as desired.

A pipe, b, also leads into the compartment A, for

Vadmitting a quantity of air sucient fori acetifyingbottom, resting on a perforated bottom, I, leaving a considerable space beneath, into which lower apartment lead air-tubes c c c c. l

In the 'acetlifier H' are also placed from 'one toy two hundred gallons of vinegar, more or less, according to its capacity. y

In 'performing my operations or process, the airtubes in the acetitier are closed, and heat or steam applied under `or around the compartment A of the generator, which causes the vapors to ascend up into the saturated shavings above, carrying with it the air which is being impelled through the pipe b', mingling with the vinegar in the eoetifier above, and converting it also into vapor, from whence it passes 11p-into -theshavin gs above, and into the pipe leadinginto the acetier; whence it passes down as vapor, through the Vertical pipe H, into the liquid vinegar in the compartment below, converting the vinegar in the said compartment into vanor also. which is conveyed through pipes into other acetiers similar to that last described, and from thence to standers asvinegar.

Whentwo of the acetifiers are employed-beside the generator, about twenty-live per cent. of the alcohol contained in the fomented mash, or dilutedalcohol, is converted into vinegar at once, and the remainder is brought into such'a condition that itis converted into vinegar in a much shorter timev than by the old process, while by employing more acetifiers the remaining alcohol can be converted into vinegar.

Having thus 'described my invention,

What' I claim, and desire to secure by Letters Pat-Y by Letters Patent, vis- 1. Mingling oxygen with a vapor intended to be acetied before the same is' condensed by injecting atmospheric air, or the prepared gas into the vessel or compartment in which the vaporis generated, substantially as described. e
